Launch from Cape Canaveral (KSC); landing on Cape Canaveral (KSC).

It was the second in a series of planned servicing missions to the orbiting Hubble Space Telescope (HST). The satellite was captured with the RMS. The crew performed several EVAs to upgrade the scientific capabilities of the Hubble Space Telescope (HST).

First EVA by Smith and Lee on 14.02.1997 (6h 42m) to replace the Goddard High Resolution Spectograph (GHRS) by the Space Telescope Imaging Spectograph (STIS) and the Faint Object Spectrograph (FOS) by the Near Infrared Camera and Multi-Object Spectrometer (NICMOS).

Second EVA by Tanner and Harbaugh on 15.02.1997 (7h 27m) in which the Fine Guidance Sensor (FGS) and one Engineering / Science Tape Recorder (ESTR) were exchanged and the Optical Control Eletronics Enhancement Kit was installed.

In a third EVA on 16.02.1997 (7h 11m) astronauts Smith and Lee exchanged one Data Interface Unit (DIU) and replaced a second ESTR by a Solid State Recorder (SSR). At last they removed an older Reaction Wheel Assembly (RWA) and installed a new one.

Fourth and final planned EVA by Tanner and Harbaugh on 17.02.1997 (6h 34m). They exchanged one of the Solar Array Drive Electronics (SADE) and installed some covers on the magnometers. After that they started to repair the thermal isolation on the HST - this was not planned, but the isolation was rather damaged.

In a final not planned EVA on 18.02.1997 (5h 17m) astronauts Smith and Lee completed repairing work on the isolation.

After the successful work the Hubble Space Telescope was again deployed on February 19, 1997 and worked fine.
